Fantastic Voyage - Idea Development

Above are a couple of concept paintings so I could get a sense of the colour schemes I'm thinking of using and if they work. I do intend to try a Indie game style animation with low poly modelling, so the paintings above are not a representation of what I intend to do.  

I wanted to see if my ideas would be viable in the time frame given - So a quick test model was made to see what the low polygon modelling would look like and what sort time it would take. The model below was kind of a speed model and will be refined if the green light is given.
